Sažetak
Sour cherry cv. Marasca is Dalmatian cultivar from XVI century. Cultivation is limited on the north and central part of Dalmatia and on the part of the islands, where it achieves the best quality of fruit, high content of dry matter and sugar respectively, agreeable aroma and intense color. Sour cherry cv. Marasca is source of biologically active ingredients, organic and inorganic compounds, dietary fi bers, aromatic compounds and high content of phenolic compounds, particularly anthocyanins and hormone melatonin. Many epidemiological studies showed that phenolic compounds have antioxidant and anti-infl ammatory properties, and they have benefi cial eff ect on human health. Marasca is rich with mentioned compounds. Physicochemical composition (total and soluble dry matter, pH value, total acidity) during ripening of cv. Marasca ecotype Recta (Cerasus marasca recta) grown in Zadar and Split area were determined. Total and soluble dry matter increased and pH value and total acidity showed little change during ripening. Th e content of phenolic compounds increased during ripening as well as content of anthocyanins, while antioxidant activity decreased with ripening. Th at indicates there was no correlation between antioxidant activity and content of total phenolic compounds.
